Abstract
A family of chiral zinc amido-oxazolinate complexes are shown to be highly active and isoselective initiators for the ring-opening polymerization (ROP) of -lactide, yielding isotactic stereoblock polylactides (PLA) with up to 0.91. This represents the highest isoselectivity observed with zinc-based catalysts for ROP of -lactide.
摘要
一族手性锌酰胺-恶唑啉配合物被证明是丙交酯开环聚合（ROP）的高活性和等规选择性引发剂，可生成全同立构规整度高达0.91的全同立构立体嵌段聚丙交酯（PLA）。这是基于锌的催化剂用于丙交酯ROP所观察到的最高等规选择性。
